The Upper Peninsula of Michigan is the northern of the two major land masses that comprise the U.S. state of Michigan. It is commonly referred to as simply "the Upper Peninsula", "the U.P.", or "Upper Michigan", and more casually as the land "Above the Bridge". It is sometimes called "Northern Michigan" by non-Michiganders, but that term is more commonly applied within the state to the northern half of the Lower Peninsula.

The Upper Peninsula is very rich in mineral deposits including iron, copper and silver. Small amounts of gold have also been discovered and mined. In the 19th century, mining dominated the economy, and the UP became home to many isolated company towns. Some mines are still active, though on a much smaller scale. Logging continues to be an important industry. Because of the highly seasonal climate and the short growing season, agriculture is limited in the Upper Peninsula, though potatoes, strawberries and a few other small fruits are grown. Tourism is the main industry.
